Maybe Mariah Carey can get away with being intoxicated when speaking in public, (like she was at the recent Palm Springs Film Festival) but most mere mortals trying to earn a living cannot. Here are some tips to make your next presentation something to pop a cork about:

1. Be prepared. Make sure you find out ahead of time what the room looks like, how many people will be in the audience and what they expect from you.

2. Have a back up. If you plan on using media in your speech, have an extra drive with your presentation on it — just in case! And be ready to go low tech, high touch if the technology fails completely.

3. Grab the attention of the audience with something catchy from the start. A funny statement, a quote, a graphic–anything that will cause your audience to focus 100% on you.

4. Be bubbly. If you don’t bubble over about your topic, the audience won’t either. Unless you are delivering bad news, speak with enthusiasm.
